Abstract
A method and apparatus are provided for transmitting and receiving control information in a wireless communication system. A method in a base station includes identifying an offset value and a number of control channel candidates corresponding to a number of control channel elements (CCEs) constituting one control channel candidate; determining indexes of control channel candidates based on the identified offset value and the identified number of control channel candidates; and transmitting the control information to the terminal through at least one of the control channel candidates in a downlink control channel. The determined indexes of control channel candidates are spaced by a value determined based on the transmitted number of control channel candidates.
